The Netherlands has integrated Chitosan Oligosaccharide into tomato greenhouse cultivation and achieved substantial yields. |
Method: Foliar sprays of 100ppm COS solution at seedling, flowering, and fruiting stages.
Results: Gray mold incidence reduced by 52%, cutting fungicide use by 40%.
Yield increase: 18% more fruits per plant with improved uniformity.
Quality upgrade: 25% higher lycopene content and 3-day extended shelf life.
Grower testimonial: “COS slashed chemical costs and helped our tomatoes meet EU organic standards, boosting export prices by 12%.”
How to Use Them Effectively
Chitosan: Seed treatment 0.5-1% solution soak (improves germination by 15%).
Soil amendment: Apply 10-15kg/hectare granular chitosan with organic fertilizers.
COS: Drought resistance 100-200ppm foliar spray during critical growth stages.
Fruit quality: 80-120ppm spray at post-flowering and fruit-swelling phases.
Avoid: Mixing Chitosan with strong acids or COS with copper-based pesticides.
